To all whom t may concern:

Be it known that we, Ln ltor Fw. FAUoi-rnn and VILLIAM M. DIXON, citizens of the United States, residingv at Richmond, in the county oi Contra Costa and State oi Californie, have invented new and usetul lmprovements in Pin rFools, ot' which the following is a specification.

This invention Contemnlates the Provision ot a tool designed to facilitate the extraction of cotter pins from bolts, particularly when the head of the pin is well seated in the slot ot the nut associated with the bolt under which circumstances it is often times a matter of great ditliculty in obtaining a proper purchase upon the pin to remove it of said parts.

ln carrying out the invention, we contemplate the-provision ot a tool which resembles a pair of pliers, wherein the jaws of the tool are relatively broad, one jaw being formed with a pair ot' tapered prongs which slightly protrude from said jaw in the direction of the other aw, the latter mentioned being `formed with notches to receive said prongs when the jaws are moved toward each other for the purpose of gripping a cot ter pin to remove it from the object with which it is attached.

Another object of the provision of a tool of the above mentioned character, wherein the prongs are arranged to permit the tool to be used either at a right angle to the bolt from which the cotter pin is to be extracted, or used in a position parallel with said bolt.

The nature and advantages of the invention will be better understood when the tollowing detailed description is readV in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this applic-ation, like numerals of reference indicate similar parts in the severalv views, and wherein:

Figure 1 is a perspective view of the tool v forming the subject matter of this invention.

Figure 2 is a view showing how the tool is used when arranged at a right angle to the bolt.

vis used when arranged parallel with the` bolt.

The tool forming the subject mattei' of' ,this invention includes a pair of crossed pivoted handles 1Q, each of which is formed with a jangthe jaws being relatively broad and arranged in confronting relation, and j 12 respectively. The tool in its entirety resembles a pair ot pliers, andis adapted to be. handled and manipulated in a somewhat similar manner. Projecting inwardly from the jaw 11 is a pair of tapered prongs 13 and 14 respectively, the prong forward edge of the jaw, while the prong 14 is arranged adjacent one side edge thereof. In other words these prongs are arranged at substantially a right angle to each other and each prong is adapted t-o ybe received by a notch formed in the other jaw. The notch for the prong 18 is indicated at 15 and opens at the forward edge of the jaw 12, while the notch for the other prong is indicated at 16 and opens at one side ofthe jaw 12. In addition to the prongs being tapered, they slightly protrude forwardly as shown in Figure 3 to facilitate the insertion of the prong through the head of the Cotter pin, and its subsequent removal from the bolt and nut indicated at 17 and 18.

When it is necessary or desirable to use the tool in a position at a right angle to the bolt 17, the prong 13 is used to extract the cotter pin 19, this use of the tool being clearly shown in l* igures 2 and 3. The jaws are opened and the tool arranged with the prong 13 arranged at one side of the head of the pin 19, and when the handles are moved together, the prong enters the head of the pin and the slot of the jaw 12. By reason of the fact that the prong has a protruding effect, it can more easily and positively be passed through the head of the pin, and during the continued closing movements of the jaw, the prong 13 being tapered has a wedging effect so as to partly extract the pin from the bolt while the pin is being engaged by the tool. After the jaws have been completely closed, a firm hold is obtained so that the pin can be subsequently extracted without any danger of the tool slipping from the pin. Then it is necessary or desirable to use the tool in position parallel with the bolt 17, the other prong 14 and notch 16 are used in connection with the pin 19, this use of the tool being shown in 13 being arranged adjacent the Figure 4. The tool is very simple in construction, and very meritorious for the purpose intended.

.Vhile it is believed that from the :tore- 'going description the nature and advantages of the invention will be readily apparent, we desire to have it understood that we do not limit ourselves to what is herein shown and described, and that such changes may be resorted tofwhenl desired as fallr within the scope of what is claimed.

Vhat we claim is: Y

l. A tool of the character described including a pair of jaws adapted to be moved toward and away from each other, one of said jaws having notches in two of its adjacent edges, and a pair or"- prongs adapted to be received by said notches when the jaws are moved toward each other, each prong being tapered and forwardly of said jaw for the purpose specified.

2. A tool of the character described oomprising a pair of crossed pivoted handles, jaws carried by corresponding ends of said handles, one of said jaws having notches in two of its adjacent edges, and a pair of prongs projecting inwardly from the other jaw, and arranged in right angular relation to each other when the jaws are moved toward each other, each prong being tapered and slightly inclined with relation to its jaw.

In testimony whereof we aiiix our signatures.
